120% for Full-Scale
The calibrated range of the ITV is the full-scale value/marketed value. This ITV
’s
range can extend
beyond the 100% mark all the way to 120% of full scale. Therefore, this ITV can deliver pressures
well beyond the calculated 100% of full-scale mark. Please note, the accuracy is not guaranteed
beyond the full-scale value. An example of where this could be useful is a process valve rate for
15PSI. Normally a 0.5Mpa ITV would be needed to meet the 15 PSI max pressure of the process
valve. Now a 0.1Mpa ITV could be used gaining 5 times better precision control of the process
valve. Please see table below for the overall values that can be set and measured for this ITV (all
values between 100% to 120% are linear)
–
Note 120% of the vacuum regulator is an impossibility
as there is not enough difference in the vacuum pressure for the ITV to function correctly.
